Covering structure



i io;

ployed. As illustratedin Figure 2,- a rela-` tively narrow strip Salso preferably of glass is imbedded in the base 3 or in the leveling layer-5, beneath the seam sealed by the cement i 6. The sheets 2 in contact with the strip 8l form; a high `friction path through which it is diiiicult for moisture to `seep.'. If desired,`

this joint between the sheets2 and the strip proof cement.

Forlight traiiic conditions the covering/1 i' maybe a linoleum, but for very heavy traliic turedz'Y ,Y v t Y 1 When itis desired., to waterproof walls',v a l fastening V device is preferably/employed toaidv in holding the sheets 2 ofthe insulating VYlayer' in place. YAs shown 'inyFigure v3, the-1 sheets 2Yare bedded on a ne texturedlayer ff of cement 5, andare additionally held to the conditions apavement comprisinga bituminous treated fibrousl sheet, such as that. defscribed in United States Patent No. -1,610,019,:f A.is preferably employed. The glass is foundVt 5to preserve theb'ond of this type of pavementv 'on a moisture pervious baise under conditions `:when it wouldfotherwise'beimpaircd by the action of chemicals present on the surface of the base ;V and ythe 'plastic pavement absorbs the surface of the glassso that it is not fracwall or base 9 b v means of a yoke strip 11 engaging the edges of the sheets. n This strip tweenthe sheets 2 is preferably'lled with a Vwaterprooiing material lfito Vinsureftightness. Anv suitable covering materlal may .Y be applied. over the insulating layer. `1

f Injsome cases it may be desirablejto use the glass sheets 2 without the top covering, and'some very beautiful effects maybe ob- 45 tained either on walls or iloorsbyiusing colfored glass in the various panels'zset `ofby -Vf the strips, or byvusin'g coloring matter in the leveling layer 5: and using a mottled orsmoky glass in the panels. By'this method underground, or. other rooms exposed tomoisture,

` that are expensive to maintain in' a sightly condition bv methods used in the past, may' be rendered permanently beautiful. i

V vThe maintenance ofuloors and runway-s is quite an item of expensej 1n thervarious {1n-. dustr1es,rand plastic pavements .1n general,

and thetypepdescribed thepatent above referredto in particularfhave demonstrated .fa marked superiority and economy over wood,v 50' concrete, andy other similar traic .surfacesA commonly usedfIt has beengvfoundidiicult,

however, to;` maintainv the bond ,between the plasticcovering and itsbase-,and particularly" whenmoi'sture is forced] into thebaseiun'der i considerable pressure. It is believedthat the Strip 11i uit 'jcinc btosaid sheets.V n f f5. A jcovering structure for floors, pave- A ments andthe like comprisinga base, a glass vsheet secured to saidbase, andra bituminous bond is destroyed by chemical agents such as alkali reacting with the bonding material to loosen the covering, or by dissolved salts carried through the base and deposited under Vthe covering to raisethe covering and break the bond, or both.

f An interposed insulatinglayer of glass will prevent such an occurrence, because it is of l'astingindeinitely even though the moisl tureis under considerable pressure beneath the base. Further-more, the insulating layer of glassis chemically. inert and'dielectric, and

itself will not deteriorate. y

In conclusion it is pointed. outthat the covering structure embodying my invention` rooms, that wouldotherwise be damp and unhealthy, dry and tenable. It is also pointed' outethattlie structure is ofparticular" valueiwhenused to preserve thebond of a 'plastic "bituminouspavement or of vva bituminousfcementingflayer on a moisture pervious base.
